Struct FontGroupFamilyTemplate 

struct FontGroupFamilyTemplate {
    template: FontTemplateRef,
    font: OnceLock<Option<FontRef>>,
}

A FontGroupFamily can have multiple associated FontTemplates if it is a “composite face”, meaning that it is defined by multiple @font-face declarations which vary only by their unicode-range descriptors. In this case, font selection will select a single member that contains the necessary unicode character. Unicode ranges are specified by the FontGroupFamilyTemplate::template member.

Fields

template: FontTemplateRef

font: OnceLock<Option<FontRef>>

Implementations

impl FontGroupFamilyTemplate

fn font( &self, font_context: &FontContext, font_descriptor: &FontDescriptor, ) -> Option<FontRef>

fn font_if_matches( &self, font_context: &FontContext, font_descriptor: &FontDescriptor, template_predicate: &impl Fn(FontTemplateRef) -> bool, font_predicate: &impl Fn(&FontRef) -> bool, ) -> Option<FontRef>

Trait Implementations

impl From<FontTemplateRef> for FontGroupFamilyTemplate

fn from(template: FontTemplateRef) -> Self

Converts to this type from the input type.

impl MallocSizeOf for FontGroupFamilyTemplate

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
